SD Memory Card Design Gets 300 MB/s Injection

Last week at IFA 2010 in Berlin, the SD Association revealed that it had developed a new, dual-row memory card design that can achieve bus interface speeds of up to 300 MB/s. That's a definite increase, as the current UHS-I technology supports data transfer speeds up to 104 MB/s.

In an announcement released during the show, the SD Association said that the new design will be used for SDXC and SDHC devices and memory cards. The design will also be fully backwards compatible, and incorporated into the upcoming SD 4.0 specification slated for an "early 2011" release.

According to the Association, new high speed interface signals will be assigned to the second row of pins. The design will not change the actual physical size or shape of SDXC and SDHC cards, and will be available in both full-size and micro form factors.

"Out innovative dual-row pin design ultimately lets consumers using equipped products to manage the massive storage capacity found on SDXC memory cards at incredible speeds," said Norm Frentz, chairman of the SD Association. “SD can now support high definition video from Hollywood movie studios, television broadcasts, or HD videos taken on your latest vacation."

    But, will the card itself match the 300 MB/s interface speed? That's enough for uncompressed 10 bit HD video, pretty insane if the card can keep up...

    Interesting. Pretty soon we won't need SDDs, just skip straight to memory cards.

    can we get some of these fast speeds affordable? sdxc sounds nice and all, but when the cards are in the hundreds of dollars it's kind of a bummer

    Only a 300% increase. Psh.
    It'll be nice when rental companies switch to something like this.

    You hit the nail on the head right there. Goody-gumdrops if the interface can hit that speed, but it's pointless if the medium can only hit a fraction of it. I doubt most of the people reading this have storage capable of saturating a SATA 2.0 interface...

    Nice to know they are at least working on it though
    Give it time and I would like to see SD cards replace Optical Disks as the only viable physical media format.
    Would make packaging, shipping, storage and production costs all a fraction what they are today, not to mention the reduction in energy in reading or writing.
    I wonder how many millions of tons of CO2 would be saved by killing BluRay & DVD and having HD Movie SD?

    im expecting a massive price increase on these cards, and ssd's should get a nice speed boost and price reduction by the time these are mainstream...i heard intel is releasing some new ones by the end of the year, i expect some massive price drops

    Isn't their some thing that makes SD cards go into a raid 0? That would be AMAZING with this. Insane speed if you raided alot of them.

    Besides the issues involved with NAND degradation. SSD's have firmware and other methods that prevent premature deterioration due to writing, standard flash memory does not. Still a complete possibility with the way technology is advancing though.

    In your face USB 3.0!
